I have banked with N&P for years ..... No problems, efficient, quick and helpful. They also pay interest on credit balances on my current account. What charges they levy (not if you are in credit) are fully explained and are fair and reasonable. They are a mutual building society (one of the few left) and any decision such as this has the support of the majority of their members or they could not do it.
The problem is give some people a stick and they start beating everyone with it. The only reason this company is bleating is that N&P have told them to p*ss off and thus stopped them from earning huge fees for "reclaiming" charges levied on those too thick to read the Ts & Cs they agreed to when they opened their accounts.
If you don't like your bank then move your account.
